Title: Cooling method and energizing method of superconductor
Inventor: OHKURA KENGO
IPC: F17C13/00
Filed: 1997-07-16
Abstract: A method is provided for cooling a high temperature superconductor such as an oxide superconductor to a lower temperature at a lower cost with a more simple system.  A superconducting coil is attached to a cooling stage of a refrigerator.  By immersing the superconducting coil on the cooling stage in liquid nitrogen, the superconducting coil is cooled rapidly.  Then, the superconducting coil is further cooled by the refrigerator.  By the cooling operation of the refrigerator, the liquid nitrogen is solidified.  Thus, the superconducting coil is surrounded with solidifed nitrogen.  The superconducting coil covered with the solidified nitrogen is further cooled by the refrigerator.  In the superconducting coil cooled to a lower temperature and covered with solid nitrogen, quenching is suppressed to allow a higher current to be conducted.
